The Price of a Passing Grade
"Wow, our teacher really does have a pretty hole, doesn't he?"
After tutoring ended and I returned home, my younger sister was nowhere to be seen, which was unusual. I took a shower and was resting on my bed when I heard the sound of the front door opening around eleven o'clock. Dazed and half-asleep, I opened my eyes and offered a weary greeting. "Hyun-seo, you're home...? You're a bit late today..."
Still in her school uniform with her backpack on, my sister kicked off her shoes and charged at me, throwing herself into my arms. I let out a stifled groan and carefully hugged her back. "Ugh, my head feels like it's going to split open, Oppa..." It was no exaggeration; she looked completely exhausted, her hair disheveled and dark circles heavy under her eyes. I opened my eyes wide in surprise and asked, "Have you been studying until this hour?"
Hyun-seo wiggled closer, burying herself deeper into my chest as she muttered, "Yeah... midterms are coming up soon. I promised you I'd study hard, so I really want to do well on this exam..."
"Ah, I see... You've worked so hard." I gently stroked her hair with affection. Perhaps feeling comforted, she beamed at me and squeezed my waist tightly, pulling herself so close that not even a sheet of paper could fit between us. When she wrapped her legs around me like a snake and held on, I started to feel a bit breathless. I patted her back, trying to signal her to let go. "Uh... H-Hyun-seo? Oppa is having a hard time, maybe that's enough..."
"No, I had a rough day, so I'm going to stay like this for an hour."
"An... an hour?"
"Yep, an hour." She answered firmly, without a hint of hesitation. Not knowing what to do, I broke into a cold sweat, eventually giving up and letting her hold me. Before long, she fell fast asleep in my arms without even changing her clothes. I looked down at her with a faint smile, but then a sudden thought struck me, and I felt a jolt of anxiety.
'...Wait, if Hyun-seo’s school has midterms coming up, that means the same goes for those girls, right? What do I do...? They don't even listen to a word I say during class... If they take the exam like this, they’re guaranteed to get the lowest grade!'
...For now, Nayeon’s mother and the other parents seemed to view me favorably, but if they saw report cards that were just as disastrous as before the tutoring started, they wouldn't keep thinking so highly of me. They would surely see it as a waste of money and fire me immediately. Then I’d be back to being an unemployed nobody, just like a little while ago... I looked down at Hyun-seo’s cute cheeks pressed flat against my body, squeezed my eyes shut, and shook my head.
'...No...! For my sister's sake, I absolutely have to avoid getting fired from this tutoring job. But how on earth am I supposed to make those girls actually listen to my lessons...? Ugh, I’m going crazy, seriously...'
As I let out a deep, soul-crushing sigh, Hyun-seo opened her eyes blearily and glanced up at me.
Today was the first time since I started tutoring that all three students were gathered in one place. It was good news that they were all present with exams just around the corner, but as I had unfortunately foreseen, the class did not go according to my plans at all.
Barely a minute into the lesson, Nayeon, who had been leaning against me while scrolling through her phone, giggled and nudged her head against me, whispering, "Teecherr~ Take it out so I can check the state of your cock~ Hehe."
"U-ugh..."
Ye-eun was lying prone on the bed with her massive breasts pressed against the mattress, blinking lazily as she watched her phone with a dazed expression. She had unbuttoned her school shirt so low—more than five buttons undone—that her navel was clearly visible. Seunghee was sitting upright at the desk, using a hand mirror to brush through her blonde hair. When she caught my eye, she gave me a pretty, beaming smile.
Being in a room with three girls in their prime made me feel even more intimidated than usual, so I couldn't say a word. I did as Nayeon commanded, fumbling to take off my pants and pulling out my erect member. Nayeon’s eyes went wide as she gulped, staring at my cock from every angle before she smirked and slowly reached out her hand toward it.
Right at that moment, I mustered a sudden burst of courage and grabbed Nayeon’s hand, which was heading for my crotch. "W-wait...!"
"....?"
Nayeon’s expression turned savage instantly, a dark shadow falling over her face. Intimidated by that look, I quickly let go of her hand and swallowed hard. '...I-I’m screwed... She’s going to tear me apart again...'
But instead of unleashing a torrent of profanity or berating me to death, Nayeon just furrowed her brow and scanned me up and down, asking in a low voice, "....Why."
Surprised by her relatively gentle tone, I turned my head, but when I met her gaze, I got scared and quickly lowered my head again. I stammered, "I-it’s... y-you guys have... exams coming up soon..."
"....So?" Nayeon yawned, lifting her arms high enough to expose her armpits, and answered with complete indifference.
I swallowed hard and continued in a trembling voice, "S-so, I thought... maybe we should start preparing for the exams..."
"....What? Exam prep?" Nayeon blinked, as if she had never heard such an absurd combination of words in her life. I hurriedly shifted my gaze to all three students and pleaded, "...I-I’ll give you everything you want from now on...! But please, just for the exam period, listen to my lessons properly...! If you keep going like this, your scores are going to hit rock bottom...!"
"Hmm...? But we’re already getting everything we want right now? Do you really think you can make us listen to your class with such a lame promise, Teacher?" Ye-eun smirked mockingly. It wasn't exactly wrong, and just as I was sweating bullets, unable to find a comeback, Seunghee, who had been looking in the mirror, suddenly raised her hand like she was making an announcement and shouted with sparkling eyes, "Oppa, I have a great idea!"
And so, about ten minutes later, I found myself completely naked, without a single thread of clothing, in front of the three girls. They surrounded me, giggling as they openly gawked at my bare body. Shivering with shame, I couldn't even lift my head, and I stammered in a tiny voice, ".....I-if I do this.... you promise to listen to the lesson...?"
"Teacher, your voice is as quiet as a mosquito, I can't hear a thing~ Hehe." Nayeon covered her mouth and mocked me, scanning my entire body with a sticky, lingering gaze.
Feeling a sense of humiliation so deep it brought tears to my eyes, I spoke a little louder than before. "...T-then I'm starting the lesson, so everyone listen up...!"
"Wait a second, Oppa. I have one more request!" Just as I was about to start, Seunghee raised her hand again, her blonde hair fluttering, and shouted. I gulped, tense with anticipation. "W-what now..."
Seunghee pulled out her phone, flipped through her gallery, and suddenly shoved it in my face, saying brightly, "Do this pose, Oppa! Then I’ll really listen to the lesson!"
"W-what....?" I stared in shock at the photo she was shoving at me. In the picture, Seunghee herself was wearing a cosplay outfit with a cat tail, lying prone with her body stretched out as if a cat were stretching. To put it simply, it was the pose of a lewd female ready to be taken from behind. I squeezed my eyes shut and shook my head rapidly. "T-t-this is a bit..."
When Ye-eun and Nayeon saw the photo, they either burst into laughter or looked disgusted. Ye-eun slapped her own thigh and laughed until she was doubled over. "Pfft... Hahaha! This is going to be a real sight to see! Teacher, hurry up and do it!"
"....Do you guys actually like this kind of stuff...?" While Ye-eun rolled on the floor laughing, Nayeon frowned, crossed her arms, and glared at Seunghee. I stood in the middle of them, fidgeting and not knowing what to do, until I finally gave up and muttered in a small voice, "...I-if I really do it, you'll listen to the lesson..."
"Yes, of course, Oppa! I'll listen super hard!" Seunghee shouted happily, pumping her fist in the air. Nayeon just kept her lips tightly sealed, looking somewhat dissatisfied.
And a few minutes later, I was lying prone on Nayeon’s bed in an unmistakable female position, my rear end stuck up in the air. Seunghee sat on the edge of the bed, watching my testicles and cock dangling in the air, snapping photos one after another. "Oppa, looking at it like this, it’s not just your cock that’s big, your balls are huge too...? They’re hanging so low, they look bigger than my fist... Amazing..."
Meanwhile, Ye-eun climbed onto my rear and sat there, using both hands to spread my asshole wide to get a better look. "...Wow, our teacher really does have a pretty hole, doesn't he? It’s not easy for even a real girl to be this clean and pink without a single hair... Teacher, are you actually a girl in real life?"
Nayeon, on the other hand, was crouching with her arms resting on my shoulders, staring at me with a savage look in her eyes. "....Hey, why is your cock standing up so straight? Does it feel good? Does it feel good to be like this, you fucking..."
"Ugh.... K-kuh..." I was so ashamed I couldn't even face Nayeon, so I squeezed my eyes shut and buried my face deep into her pillow.
